摘　　要：作为生产钨/铜金属板的主要方法之一,热爆炸焊接具有传统方法所不具备的优势,但在实际生产过程中热爆炸焊接自身存在瞬时性、危险性等缺陷.为研究钨铜双金属板热爆炸焊接机理,以钨/铜金属板为研究对象,利用ANSYS/LS-DYNA有限元软件对其爆炸焊接过程进行了数值模拟.计算并建立了爆炸焊接窗口,对模拟过程中的复板竖向位移、碰撞压力和碰撞速度进行了分析,模拟结果与实验及理论计算结果吻合较好.采用SPH法建立钨/铜二维斜碰撞模型,得到了钨/铜爆炸焊接复合板结合界面的波形,模拟结果与实验所得金相界面较为一致.As one of the main methods of producing W/Cu metal plates,thermal explosion welding has advantages that traditional methods do not have,but in the actual production process,thermal explosion welding itself has defects such as being transient and dangerous.In order to study the thermal explosion welding mechanism of tungsten-copper bimetallic plates,this paper takes W/Cu metal plates as the research objects,and uses ANSYS/LS-DYNA finite element software to carry out the numerical simulation of the explosion welding process.The explosion welding window is calculated and established,and the vertical displacement,collision pressure and collision velocity of the double plate during the simulation process are analyzed.The simulation results are in good agreement with the experimental and theoretical calculation results.The SPH method is used to establish a W/Cu two-dimensional oblique collision model,and the waveform of the bonding interface of the W/Cu explosive welded composite plate is obtained.The simulation results are consistent with the experimental metallographic interface.
